6 Claims.

This invention relates to improvements in valves and/or valve casingmountings and their operative in-clusion in conduit systems,particularly, in conduit systems such as described and claimed in mypending applications for Letters Patent, Serial No. 511,366, ledNovember 22, 1943, now Patent No. 2,570,246, October 9, 1951, and SerialNo. 47,851, filed September 4, 1948, said improvements being similar,and so, pertaining and related to the invention shown in my applicationfor Letters Patent Serial No. 583,879, iiled March 21, 1945, nowabandoned.

It is an object of the invention to provide a valve for the inner pipeof a jacketed conduit line whereby to control and/or regulate the flowof matter therethrough, the same being so mounted as to provide anunimpeded or uninterrupted way about and by it and between the innerpipe and the conduit line jacket or casing, thus permitting multiple owthrough the lineone, through the inner pipe, and another, through theiiow-way between the inner pipe and the jacket, or, in other instancesof installation and uses, allowing for the spa-cing and insulation ofthe inner pipe from the jacket or casing.

Another object of the invention is to provide a control valve andmounting for jacketed conduit lines, the valve being operable orregulatable at a pointremote therefrom, as when an equipped line issubterranean or submarine installed and it becomes desirable ornecessary that the above surface operation or regulation of said valveshall be effectable, or that said valve shall be operable at a pointbeyond the same.

Yet another object of the invention is to provide a valve installationof the indicated character which will eliminate the necessity and costof constructing manholes or kindred or similar Vways of ingress oregress to and from the same,

as for adjustment, operation, regulation, repair or replacement.

The invention also aims to provide a jacketed valve installation of suchconstruction that the sa-me will in no/manner impede or otherwiseprevent a maximum flow of matter thereby through the line jacket orcasing; also, will prevent leakage from the inner pipe and/or its jacketor casing.

Furthermore, it is an object of the invention to provide a jacketedvalve in which the casing or jacket housing the same can be convenientlyand quickly opened to. permit` working or like access tothe valve, andwhich can be as conveniently and vquickly closed, all with a minimum ofdisruption of the. line maintenance and/or operation.

The foregoing, as well as other objects, advantages andmeritoriousteachings of my invention, will be in part obvious and inpart pointed out in the following detailed disclosure thereof, whentaken in conjunction with the accompanying drawings, it being understoodthat the forms of the invention presented herein are precise and whatare now considered to be the better modes of embodying its principles,but that other modifications and changes may be made in specificembodiments without departing from its essential features.

In the drawings:

Figure 1 is a vertical longitudinal section through one form of myimproved valve and/or valve casing mounting wherein the valve casinghousing is shown to be of the T-type.

Figure 2 is a vertical transverse section taken on the line 2 2 ofFigure 1, looking in the direction in which the arrows point.

Figure 3 is a side elevation, partly is section, of a modified form ofvalve and/or valve casing mounting, in which the T-type of valve casinghousing is provided with an extended or elongated vertical jacketadapted to house the valve bonnet and operating stem in such a manner asto allow for its operation from a comparatively remote point.

Figure 4 is a View similar to Figure 3, illustrating a somewhat modifiedform of the invention, wherein an elongated sleeve or housing isextended from and beyond the valve casing and is adapted to house thevalve stern and its operating handle therewithin, and

Figure 5 is a verti-cal longitudinal section of another modied form ofmy improved valve and/or Valve casing housing construction adapted toreceive and support therein a rotary plug type of valve; a bottom coverbeing provided to the valve casing housing whereby to facilitate accessto, and removal or replacement of the rotary valve plug core. Referringin detail to the drawings, particularly to the Figures l and 2 thereof,the invention, generally. comprises a sectional valve casing housingindicated in its entirety by the numeral I, a valve casing 2 from whicha valve connected operating stem 3 extends through an appropriate andhereinafter more fully described way in the housing, and inner pipes 4received in and extending through casings or jackets 5 in radially andpreferably equi-spaced relation to the walls thereof.

The valve casing housing l consists of a pair of complementally shapedand sized T-shaped sections 6 and 6', made of cast iron, steel or otherare integral with or flxedly mounted on the opposite longitudinal sidesof the body sections B and 6. Said flanges have complemental openingsformed in the same adapted to receive connecting bolts III therethroughfor an obvious purpose. If desired, packing I! can be arranged betweenthe flanges.

Correspondingly curved and/or complemental flanges I2 are integral withor otherwise fixed to the outer ends of each of the aforesaid branchesof the T sections 5 and 6 and have suitably spaced openings therein, thepurpose of which is hereinafter described. At this particular point, itwill be noted especially on reference to Figures 2 of the drawings, thatwhen the T-shaped sections 6 and 6 are in their assembled or juxtaposedrelation, the aforesaid curved complemental flanges I2 are of circulardisposition, permitting their use in connecting the flanges of housingsor jackets 5 hereinafter described to the same.

The Valve casing 2 housing a suitable valve (not shown), as for example,a gate, globe, or other conventional type of valve, is received in thehousing I in the manner shown in Figures l and 2 in spaced relation tothe interconnecting or communicating ways therein and Preferably, thevalve casing is disposed longitudinally of and in the lower way of thehousing so that its opposed open ends communicate with those of saidway.

A valve stem bonnet I3 is suitably connected to the upper side of thevalve casing 2 and extends through and beyond the intermediate way 8 ofthe T housing I.

Engaged over the upper or outer end of the intermediate way of thehousing is a cover plate I4 having openings formed therein aligning withthose in the adjacent anges I2. Connecting bolts I5 are engaged throughsaid openings for an obvious purpose.

Of course, a suitable gasket or packing I I can be provided between thecover plate I4 and the adjacent fianges I2.

The cover plate I4 has a screw-threaded opening formed therein mediallyof itself whereby to receive and retain the shell casing of a suitablestuing box I6. For manifest reasons, the upper portion of the valvebonnet I3 is engaged through and extended beyond said stuing box andcover plate I4. Its outer and free end is equipped with suitable packingand a nut II. Thus, said bonnet, and in consequence, the Valve casing 2will be eiectually and rmly supported in the aforesaid spaced relationwithin the T housing I. Also, leakage of gases, fluid, liquids, etc.,through the cover plate will be prevented.

The hereinbefore identified valve stem 3 is rotatably received in andthrough the bonnet I3, having its lower end operatively connected to thevalve (not shown) in the casing 2. A handle I8, or like means, isconnected to the extended upper end of the stem for an obvious purpose.

The ports in the valve casing 2 opening into the housing way I have theadjacent ends of the inner pipes 4 engaged and/or secured therein.Hence, flow of matter through said pipes can be therethrough.

selectively controlled or modulated by operating the Valve in the casing2 through its stem 3.

To connect the opposite ends of the T housing I to adjacent ends of thecasings or jackets 5, collars or circular flanges I9 with outsidediameters substantially corresponding to those of the now circular angesl2, are threadedly engaged or Votherwise xedly carried on said ends ofthe casings. The flanged casing ends are juxtapositioned with relationto said T housing ianges, suitably gasketed as at I I', and connectedthereto by bolts 20 or other appropriate means.

In some installations of the T housing I, anchor plates with diameterssubstantially corresponding to the outside diameters of said flanges I2and I9, indicated at 2 I, may be employed. When used, an anchor plate ispositioned between the flange I9 of one casing 5 and the adjacent angesI2 of the T housing I. It is then secured in fixed position by passingthe aforesaid connecting bolts 2Q therethrough, in the manner clearlyshown in Figure 1 of the drawings.

Various forms of anchor plates may be and are used in connection withthe invention. In the present embodiment, the anchor plate, as statedabove, is of circular formation; it is preferably made of cast iron,steel, or other suitable material; it is formed with a centrallydisposed opening therethrough for receiving an adjacent portion of oneof the inner pipes 4 and is then welded or otherwise joined to saidpipe, as indicated at 22. Also, suitable ports or ways 23 are formed inthe plate and serve, with its installation as above described, to permitof the unimpeded iiow of matter in and through the flowway provided andconstantly maintained between the inner pipes 4, their casings orjackets 5 and the inner side walls of the ways provided in the T housingI.

It will be understood and appreciated by workers skilled in this artthat the usage of anchor plates, as above outlined, may be varied in thenumber or instances of their usage and in the rela-tive spacing betweenthe same within the casings or jackets 5 and the housings I. The primeutility of these anchor plates, of course, is to prevent excessiverelative longitudinal movement between the inner pipes 4 and theircasings or jackets 5, yet sufficient movement to positively preventexcessive stressing of the same to such an extent as to bring abouttheir fracturing or rupturing or other unwanted deterioration. But, inno instance of such anchor installation will that installation impede,impair, or otherwise interfere with a full and complete flowing ofmatter in the flowways between said inner pipes 4 and their casings orjackets 5 and through the T housings I, all as above described.

In Figure 3, I have shown a modified form of my invention. It isespecially advantageous for use in submarine, subterranean or in otherinstallations where operation of the control valves in the Valve casings2 within the T housing I need be effected at a distance from or remoteto the equipped conduit lines. Herein, the sectional T housing I,receiving the valve casing 2 therein, has an extension intermediately ofthe same and the to-be-described cover plate I4'. Said extensionconsists of a tubular body or sleeve 24 of the desired or requiredlength having its opposite ends flanged as at 25. One of the flangedends is juxtapositioned with relation to the flanged end I2 of thehousing I', gasketed as at 26, and connected thereto by bolts 2l. Theremaining end of the extension 24 has the cover plate I4 engaged overand connected thereto by bolts 115'. This cover plate, linfturn, is:formed with a substantially centrally disposed 'opening -y.which istted with astuingbox llB.

Itis preferable that the extension-:24 shall .be

'constructed of .cast iron, fsteel, :or such other :material as shall.possess :it-he .necessary stressrey:sistant andenduring properties.

An elongated:Valvestembonnet L3 is-.re ceved longitudinally throughLtheextension Zillinf-spaced relation to the .walls v thereof. The -lowerend of said'bonnetis connected .-to the upper sside :of :the .valvecasing '.2' .while .fits upper .end portion i-s .engaged throughthecover plate y provided stufrng vbox I 6 yand. equippedwith .asuitable `.pa-cli- :ingfnut I1. lower end to :the '.valveinot shown):ain thewvgalve rcasing 2 is rotatably received in ;and'.,thr ough.theelongatedbonnet i3' and has itsupper zenjd extended therebeyondwhere vit `isfsqua1 e :l,.as.at 28, or otherwise prepared to;mount ahandle or other rotation facilitatingdevice, notshown.

Thus, operation of tthe valve within its casing r2' by meansgof thevalve stem 3 rotatable-,in and extended fromthe ,upper end of the velongated .bonnet i3 from .a `point removedior Vremote jfrom said .valvewill be permitted. Moreover, since -the valve stem is extended beyondlthe tubular body .or sleeve 24 :and its cover plate 114'.. the vflowwaybetween the inner pipes .4 and thefcasings-5,.and the valve bonnet 1 3and the walls of v the tubular Ybody f will .be maintained closedagainst "leakage .or other foutflow of matterfrom for1beyond the same.

vA further rnodication .of the .above described :tubularbody `or .sleeve.construction l.may ibe, and 3*..

under some conditions-of.usage,. etc., will1be prefi- Yerable, .such forexample, as that I form of the vinvention shown vin .Figure s4 of V theaccompanying drawings. Herein, the 'tubular ,body .243, vof

Herein, I have shown across-'typeof housing rlb consisting ofcomplemental .cross-sectionally semicircular 'longitudinally joinedfsections ,having 'crossed ways iin and `through :the ,fsame openingvonto their opposed ends. .Said :opposedfenjds are flanged, as .at 12b,so .that with :assembly fand connection of the :housingsectionin themanner shown in said Figure :5, the .flanges 'will .be of -circularform.Certain of theseflanged opposed ends l2b have the .flanged ends .-I-SlDof casingsor jackets 5b connectedthereto by.bolts:20b,.welding,

or other means.

.One of .the remaining .opposed iflanged X.open Vends-of the housing:has .acover orlclosure 1plate .2 9 a engaged .thereover and securedthereto :bybolts "30, or like means; l`said .plate ,preferably :havinga=A fyalve stem '3Q connected at its f f6 :.drainSl .connected `to :and.communicating-'with thehousing interior-for an vobvious purpose. The:other .thereof has .1a :cover plate 141 engaged thereover :and:connected vthereto by bolts 15b. This plate .hlb is formed with a:substantially :central opening fitted with a suitable stu'flingl vAVvalve casing 2b adaptedto and receiving a .conventional lform of plugor core valve is arzranged withinthe cross-housing lb, as is clearlyshown in said Figure f5, having agremovable bottom `or'plate '32, topermit removal vof .said valve '(not'shown) .for inspection, repair,replacement, --etc., via the adjacent open end of Asaid housingnormally. covered .by theplate 2 9. A valve vopertating Vstem 3'3 isconnected to land extends upawardlyforverticallyffrom the-valve housedinthe valve casing v2b through the stuiiing box lb, yaforesaidyto a.point-above 4and beyondthesame. If desired, the extended outer or upperend of this stern Y33 maybe squared or otherwise treated, v-asindicated'at 34, topermit the connection and securing of Va suitabletype of operating handle (not shown) thereto.

Because of the engagement -of the stem v33 through Athe .stuffing :boxIflb, it will -be under- .stood :and yappreciated that-the valvecasing?b will be accordedaipartial support for retaining it inthatintermediate position within the cross- .housing Ib shown in the drawing:Figure v5.

Inner Apipes lb areconnectedto andicommunicate with the opposed ports of,the plug `valve casing 2b. These pipes-.are disposed longitudinally. ofand 4through the ,horizontal opposed ways of .the crosshousing :Lb .into`and y.through the .casings 5b.

SAn anchor plate g2 Ib may be and preferably is interposed between .and,angedfend 19h of -one .of .the lcasings 5b andthe Vadjacent flangedyend {2*} of said cross-housing. .Said anchor is im- Yrnovably secured-in the stated position by means of the vhereinbefore described bolts20b which pass therethrough, Vwhile Vthe adjacent inner pipe 4b rathersnugly engages through a central opening .in 1the plate. Thus, an,additional supporting means is provided the innerpipe and/or pipes Ab,retaining themin the radially spaced relation to the casingsb and .thewalls of `the horizontal ways of the housing Jb, .ensuring y.a.continuous uninterrupted or ,unimpeded flowway, such as .hereinbeforeexplained. Also, the anchor plate is -welded to adjacent portions of theparticular inner pipe 4b passed therethrough, as indicated 211,22.

The .anchor plates .2 l and .2.1 b .employed in ythe heretofore.described yembodiments of my invention may, in some instances, bedispensed with, .more especially, .their usage may .be .dispensed withwhen vthe .distance between the conduit ,line installed valvecasinghousings or jackets is such that support of the inner pipes of said linein .eachofsad housings or jackets is unneeded, .i.e., the .number ofanchor -plate installations may be v accordinglyreduced. It isimportant, however, that the inner pipes of -theconduit line .and :thehousing or jacket .installed valve casings of the innerjpipesof saidline shall be supported in the vhereinbeiore described vradially spacedrelation to the inner sidewalls of theccnduitline casings or .jackets.and housings whereby to ensure .the .also heretofore describedcontinuous and unimpededflowway therebetween. To such end, I-wish topoint out that the engagement of the valve stems and valve stem bonnetsthrough the-stuffv:in g .boxes .of .the Valve casing housing oriacketcover plates I4, I4', and |41 is such that their respective valveAcasings 2, 2' and 2b will be most effectually retained in said spacedrelationing support; moreover, that the secureness of such support ismaterially improved upon by the installation of the aforesaid anchorplates 2l and 2|b in the valve casing housing or jackets l, l', iil andIb. That is to say, the said valve casings are aforded dual supportingmeans andso, their retention in the spaced flowway ensuring position orrelationship is substantially ensured.

While I have hereinbefore described my invention adapted to a T-housingand a cross-housing, also to different forms'of valve stems andoperating handle housings or jackets, it is to be understood that thesame may be embraced in/ or by further types and modified forms ofhousings and/or couplings and valve stem jacketing means. The essence ofthe herein disclosed and later claimed invention resides in the main, in(1) housing or jacketing an inner pipe flow control or regulating valve,regardless of the type thereof, in a housing or liacket of suchconstruction as will permit its installation, inspection or repairing ina conduit line with a minimum of disruption to that line, itsconstruction, its bedding or laying and its operation; (2) in permittingaccess to be had to the interior of the valve casing housing with aminimum of effort and a mimimum of time and with the least possibleinterruption of the line operation; (3) in so arranging and supportingthe valve casing and its valve in the housing or jacket as to space andpositively retain the same spaced from the walls thereof, thus ensuringthe forming and maintenance of a clear and uniinpeded flowway thereby,i. e., a fiowway between the outer sides of the valve casing andadjacent connected portions of the inner pipes of the conduit line, andthe inner sides of the valve casing housing or jacket and adjacentconnected portions of the casings of said conduit line; (4) inpermitting the control or regulating operation of the valve casingretained valve in the inner pipes of the conduit line withoutinterfering with the continuing flow or passage of matters through theaforesaid flowway; (5) in permitting the valve control or regulation, asabove, at points remote to or beyond its point of installation, or inother instances, in proximity thereto, and (6) in the novel constructionand operational disposition of the pipe anchors in said conduit linewhereby they serve to anchor the inner pipe and casing lines againstexcessive and possibly damaging relative longitudinal movement, as bytheir expansion and/or contraction, and at the same time, provide theinner pipe or pipes with sure and enduring support ensuring theirpermanent spacing from the housings or jackets receiving them and hence,permanent flovvways therebetween.
